Patent CA-2311110-A1 (CA)
Inventor: CHENG YIHAO
IPC: G02B6/32
Filed: 2000-06-09
Abstract: The present invention relates to an optical coupling between an end of an optical fibre and an end of a lens, which provides a reliable joint with a determined spacing and angular orientation. The optical coupling permits movement of the end of the optical fibre relative to the lens in at least two alignment directions. Advantageously, the present invention permits movement of the end of the optical fibre relative to the end of the lens in a direction perpendicular to the optical axis of the lens, before the optical coupling is secured. The optical fibre within an optical fibre tube/ferrule and the lens are secured within separate sleeves and the sleeves bonded together. The end of the optical fibre and the end of the lens are optically aligned before being secured in place relative to each other.

Title: Method and apparatus for the highly accurate determination of the filling level of a product in a container
Inventor: SPANKE DIETMAR
IPC: G01S7/40
Filed: 2000-07-06
Abstract: The invention relates to a method for the highly accurate determination of the filling level (q) of a product (4) in a container (2), measuring signals being transmitted in the direction of the surface (5) of the filled product (4) and reflected at the surface (5) as echo signals and the filling level (q) in the container (2) being determined by evaluation of the amplitude values (A) and phase values (.PHI.) of the reflected echo signals by means of a pulse delay-time method.      Furthermore, an apparatus suitable for carrying out the method is proposed.      The invention is based on the object of proposing a method and an apparatus which permit highly accurate filling level measurements in containers (2), even if multipath propagation or multimode propagation occurs.      The object is achieved by compensating for errors which occur in the determination of the filling level (q) and are caused by interference signals which interfere constructively or destructively with the echo signals reflected regularly at the surface (5) of the filled product (4).

IPC: C01D15/08
Filed: 1998-12-07
Abstract: Disclosed are methods for preparing high purity lithium carbonate which can be used for pharmaceutical applications, electronic grade crystals of lithium or to prepare battery-grade lithium metal. Lithium carbonate as commercially produced from mineral extraction, lithium-containing brines (2) or sea water, in aqueous solution is used as a feedstock and reacted with carbon dioxide (3) under pressure to form dissolved lithium bicarbonate. Impurities in the lithium carbonate feedstock are either solubilized or precipitated out.  Dissolved impurities are physically separated from the lithium bicarbonate using an ion selective means (F), such as an ion exchange material, or by liquid-liquid extraction. Purified lithium carbonate is then precipitated (G).

Patent CA-2319585-A1 (CA)
Inventor: CHARNY ANNA
IPC: H04L49/111
Filed: 1999-02-10
Abstract: A switching method and apparatus operates as a work conserving network device.  An arbiter using an arbitration algorithm controls a switch fabric interconnecting input ports and output ports. To switch cells, a virtual output queue of an input port is selected that corresponds to an output port with a lowest occupancy rating and a request is sent to this output port. In a greedy version of the algorithm, input ports may send requests to the lowest occupied output port for which they have a cell. In a non-greedy version, requests may only be sent if that input port has a cell for the lowest occupied output port in the entire network device. An output port that receives one or more requests from input ports uses an input port selection algorithm to select an input port from which to receive a packet. After as many input and output ports are matched as is possible in a phase, the packets for those matched ports are transferred across the switch. The switch fabric operates with a speedup of only twice that of the input port data rates and is still work conserving.

Patent CA-2333549-A1 (CA)
Inventor: IAKHNINE VLADIMIR ZORIEVICH
IPC: B01J8/06
Filed: 1999-06-09
Abstract: Methods are disclosed for constructing packed-bed and monolith reactors/converters, which are more resilient against process disturbances than their conventional counterparts. These stabilized reactors have a reduced tendency to develop, in response to accidental or planned changes of operating parameters, transient hot spots which otherwise can compromise safe and economical reaction operation. The invention involves creating conditions under which transient heat waves that originate from the process disturbances propagate in different radial zones of the reactor with different speeds. As a result, they accumulate phase-shifts relative to each other and interfere destructively through intra-reactor radial heat flows. This constitutes the adaptive mechanism of suppression of the noxious high-temperature waves in exothermal reactors and effects their enhanced operational stability. The area of applicability of stabilized reactors includes chemical and petro-chemical industries as well as automotive (car catalytic converter), environmental (VOC  incinerator) and power/heat generation (catalytic combustor) applications.  Advantages of the SR are enhanced safety and life span of catalyst and other reactor components, and in production applications - improved throughput, selectivity and product quality.
